What is a pocket air filter?
A pocket air filter, also called a bag air filter in HVAC applications, uses multiple media pockets attached to a frame. Primary and medium filters address particulate requirements; carbon-media pocket filters address defined odor or gas-phase requirements and need a separate application assessment.

Medium-Efficiency Bag Filters
Nonwoven pocket filters for finer particulate-filtration requirements.
Literature grades
F5 / F6 / F7 / F8 / F9
Media
Composite nonwoven
Frames
Aluminum alloy / galvanized steel / Custom
Activated Carbon Pocket Filters
